To all whom it may concern:

Be it known that I, B. Amman', a subject of the Sultan of Turkey, and aresident of Syracuse, in the'eounty oi Onondagal and State of New York,have invented a certain new and useful Gage, of which the following is aspecification.

This invention relates to gages, and has for its object a particularly1simple and etlicient construction by which the gage casing is attachedto a support or dash board andV bywhich the mechanism-is Vreadilyassembled in the casing. v

In describing thisl invention, reference 1s had to the accompanyingdrawing, in which like characters designate corresponding parts on allthe views.

Figures 1 and 2 are front and rear eleva.- tions of this gage, thecontiguous part 'of a support as a dash board heilig shown.

Fig. 3 is a vertical sectional view, partly in elevation, takencentrally on Fig, 1.

F ig.V l is a detail view of the body supporting the gage mechanism.

This gage comprises a casing open at its front and rear ends' and havingopposing shoulders or collars on its periphery, a crystal closing thefront endof the casing, and a body supporting the gage mechanism movablethrough the rear end of the casing, one of said collars being movabletoward and from the other for clamping the casing in the hole of theVsupportl as a dash board.

l is the casing which, is cylindrical in form and fits into a hole inthe support or dash board 2. Said casing isopen at its opite ends and isformed with an internal annular shoulder 3 at its front end, and isinteriorl"V and peripherally threaded at its rear en 4 and 5 are `theopposing shoulders or ilangeson the casing, the front shoulder -i beingfixed and formed integral with the cas'- ing,-and the rear shoulder -5threadin on the rear end of the casing toward and rom the shoulder 4.The shoulders 4, 5 clamp be-V tween them the margin of the dash boardaround the hole in vvhich the casing is lo catal.

6 is the crystal movable through the rear end of the body against theshoulder 3, the crystal being held 1n position by a retaining ring 7located in an internal groove 8 in the rear of the shoulder 3. The rm 7shoulders at its rear side against the si e ofthe annular groove inwhich it seats and as the ported bv thebody, and

ring is thicker groove is deep, it extends out of the groove.

The ring shoulders at its front side against the margin of the rear-face'o the crystal 6, andcoacts with the internal beveled shoulder 3which engages the margin of the beveled edge of the lens 6, to hold saidlens in pOSition..

9. Vis the body for supportingthe gage mechanism, said body being cupshaped and having its rearportion threaded for turning in the internlthreads at the rear end of the casing.' The. iront of the body is closedbya dial l0 over which moves aliand 11 operated by the mechanism in thebody 9. The closed rear .end of the body 9is pro'- vided with a nipplefor attachment to a tube which is connected to the'pump, oiling.

Gage mechanismcomprising a casing open atits ends and having opposing peripheraldanges, one being fixed and the other threading on the casing,.a crystalat the front end of the casing, means orholding the crystal in intovthecasing through the'rear end thereo said body closing the end 'of thecasing and being located entirely Within the same and gage mechanismcarried by the body, l

substantially asl and for the purpose described.

3. A gage comprising a. cylindrical casin open at itsrear end and havingfront and rear opposing peripheral flanges, the flanges being vlocatedon in posi""on or wall, the front flange rear fla-nge threadin on thecasing, the

particularly advantageous vin that it is economical of manufacture andcan the casing, a body threading 1 the 4periphery of thebody to clampthe body toa' support;

being fixed and the sof'- its rear end and having an opening casing alsohaving anmterior annular shouli i Y www? against said shoulder, and acup shaped body Y s upported by the body and movabe in the body throughsaid real' end and having as `and`for the purpose esoribed.

' -testimrony whereof, I have hereunto threaded .connection therewith,substantially signed my name, in the presenoe of two atl tesingWitnesses, at Sy1-a,f:usei in the county of Onondaga, and State, of NewYork, this 27th day of October, 1914.
